application filed September 21, 1926. Serial lilo. 57,568.

My invention relates to newand useful improvements in electrical vibrators, and has for its object the provision of an'improved construction of this character, which is capable of economical manufacture and is highly eflicient in use.

Other objects will, appear hereinafter.

The invention consists in the combinations "and arrangements of parts hereinafter described and claimed. 7

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

The preferred form of construction as illustrated in the drawings comprises asuitable casing 10 having a removable cover 11, said casing being of an elongated rectangular shape andadapted and arranged to constitute a hollow handle. Arranged in the casing 10 is an electro magnet 12 arranged to be .supplied with alternating current through feed wires 13 through a leaf spring switch 14 carrying a button or flange 15 projecting laterally through the side wall of casing 10 in position to be pressed by the thumb of the operator to close the circuit through the ele'ctro-magnet 12 when desired. Gooperat- I ing with the magnet 12 is a vibrating armature 16 pivoted at 17 on a mounting block 18 which in turn is pivoted at 19 in the easing 10. An adjusting screw 20 is threaded in the block 18 and swiveled in the side wall of casing 10, a compression spring 21 being interposed between the block 18 and said side well. By this arrangement it will be noted that the end of the armature 16 may be nicely adjusted with reference to the magnet 12. The armature 16 is operatively connected by stud 22 to the central portion of the leaf spring 23,-which is mounted at' one end on a supporting post 24 secured to the side wall of casin 10. 'The other end of spring 23 is attache to adjust-able block 25 slidable inthe socket 26 on the side wall of casing 10.

The block 25 isthreaded. on an adjusting screw 27 and cooperates with the compression spring 28 whereby the tension of the leaf spring23may be nicely adjusted, as deture 16.

5 sired to regulate the: operation of arma- [The armature 16 is j provided with a laterally turnedend 29 carrying a pin 30 pro'-.

jectin'g through a slot 31 in a partition wall 32 atthe forward end of the casing 1Q. The pin 30 engages a slot 33in theupper end of an oscillator lever -34 pivoted, at 35 to the partition wa l 32. The casing 10 isprovided I i at its forward end-with a lateralextension- 36 and the partition wall 32 forms a transverse chamber -extending across the forward end of said casing. The transverse chamber thus formed is provided with a removable cover 37 giving access to the parts within. A supporting r ..transve-rse chamber and a block 39 is arame 38 is arranged in said ranged to slide in suitable; guides 40 on the bottom of said frame. An arm 41'is rockingly connected with the block 39, as shown,

and projects upwardly through suitable slots vibrations-.of the armature 16 are caused tooscillate the lever 34, the eifect of said vibrations being multiplied and transmitted to the block 39eausin'g said block 39 to reciprocate laterally in its guides. The block 39 is provided with a downwardly extending threaded socket44 projecting through a slot in the bottom of the chamber 36. and adapted and arranged. to receive and engage a threaded stem 45-on a member 46 as shown. The mem-' ber 46 may be any suitable or desired vibrator appliance, such as a rubber massage contact piece, an eraser or other desiredappliance which it is desired to vibrate at high speed. In this way a very simpleandeffective device for vibrating various appli ioo ances is provided which is ca able. of eco-' nomical manufacture and is highly eficient in' use.

While'I have illustrated and described the preferred form of construction for carrying a Patent is: I

. from the spirit of the invention.- I, therefore, do not wish to be limited to the pre-' appended claims.
